Kyle Sandilands celebrates son Otto’s first birthday with wife Tegan Kynaston and celebrity friends including Jackie ‘O’ Henderson and John Ibrahim

He may only be a year old, but that doesn’t mean Kyle Sandilands hasn’t spent the money for his son Otto’s birthday party.

While the KIIS FM host joked that it was going to be a “watered down kind of party,” it seemed no expense was spared for the $25,000 jungle-themed birthday party.

On Saturday, Kyle’s celebrity friends and his wife Tegan Kynaston arrived in their happy rags at his Bellevue Hill mansion to celebrate baby Otto’s first birthday.

Kyle’s co-host Jackie ‘O’ Henderson appeared in high spirits as she entered the lavish party with a neatly wrapped gift for the birthday girl.

The presenter, 48, looked stunning in a mid-length white floral dress.

She kept her long blonde locks in a loose curl while accessorising with oversized black sunglasses.

Kyle revealed last week that he spent a whopping $25,000 on his son’s first birthday party.

The shock jock even got a party planner for the day, with 24 kids and 38 adults all invited to celebrate the youngster.

“It’s only $25,000,” Kyle said at the time. “It’s a watered-down party.”

Newscaster Brooklyn Ross asked Kyle in disbelief if that claim was a “joke,” while co-host Jackie “O” Henderson sarcastically called the party plans “low-key.”

Kyle said the exorbitant number didn’t include all of the other party supplies wife Tegan bought for the party.

‘Like the lollipops and the bonbonierri and the plates and all those funny tablecloths. These are eight-foot tablecloths,” he said.

Kyle joked that he was under strict instructions from Tegan to get out of his room to “associate” with guests during the festivities.

“I said, ‘Do I have to get out of my room?'” and Tegan said, “Yes,” Kyle explained. “I have to deal with the visitors.”

The KIIS FM star fell in love with Otto in his first year as a father.

He gushed about the toddler during an interview with Daily Mail Australia last October.

“I used to watch hours and hours of TV, and now I just sit there and watch him and he’s a real joy,” he said.

‘I’ve been at home all the time and I really liked that. I’m home more now than during the lockdowns so we’re enjoying every second.

‘I’m quite happy actually. I can’t imagine being happier.’

Kyle admitted that he never dreamed of having kids, but now he’s “thrilled” that he decided to take the plunge and become a father.

After the birth of son Otto, Kyle tied the knot with a no-cost ceremony at the Swifts mansion in Darling Point, Sydney.

Kyle reportedly splashed $1 million on the event which included Prime Minister Anthony Albanese and leading showbiz figures there.
